System, terminal, and method for providing a service using near field communication

Abstract

A terminal includes a data receiving unit to receive data from a first target terminal via near field communication (NFC); and a data processing unit to process service information from the data received from the data receiving unit. A method includes establishing a connection via NFC; receiving data via NFC; determining if a service is provided from the data; if a service is provided, determining if a service usage history information update is set; and if a service usage history information update is set, updating the service information of the provided service; and if the service usage history update is not set, initializing the service information. A system includes a terminal with NFC capability; a first target terminal with NFC capability, wherein the first target terminal provides the service.

What is claimed is: 
     
       1. A terminal, comprising:
 a data receiving unit to receive data from a first target terminal via near field communication (NFC); and 
 a data processing unit to process service information from the data received from the data receiving unit, 
 wherein if the data receiving unit communicates with the first target terminal, the data processing unit updates the service information, 
 wherein the service information comprises a standardized format, and 
 wherein the service information comprises: 
 a region to store commands for the data processing unit; 
 an authority status; 
 an identification for the terminal; 
 a list of the services provided; and 
 an availability of the services provided. 
 
     
     
       2. The terminal according to  claim 1 , further comprising a data storing unit to store the service information. 
     
     
       3. The terminal according to  claim 1 , wherein the data receiving unit receives second data from a second target terminal via near field communication (NFC), and
 the data processing unit updates the service information with the second data. 
 
     
     
       4. The terminal according to  claim 3 , further comprising a data transmitting unit to transmit updated service information to the second target terminal. 
     
     
       5. The terminal according to  claim 1 , wherein the service information is a record of a payment made by the terminal. 
     
     
       6. The terminal according to  claim 1 , further comprising a service status processing unit to manage a status of the service information based on a usable time associated with the service information. 
     
     
       7. A method for communicating data via near field communication (NFC), comprising:
 establishing a connection via NFC; 
 receiving data via NFC; 
 determining if a service is provided from the data; 
 if a service is provided, determining if a service usage history information update is set; 
 if a service usage history information update is set, updating the service information of the provided service; and 
 if the service usage history information update is not set, initializing the service information. 
 
     
     
       8. The method according to  claim 7 , wherein the service is provided by at least two target terminals. 
     
     
       9. The method according to  claim 7 , further comprising:
 communicating the data between a terminal and a first target terminal via NFC; 
 providing the service if the terminal is in NFC range with the first target terminal, the service being associated with the service information; and 
 updating the service information during the providing of the service. 
 
     
     
       10. The method according to  claim 9 , further comprising:
 communicating the data between the terminal and a second target terminal NFC; 
 providing the service from the second data if the terminal is in NFC range with the second target terminal, the service being associated with the service information; and 
 updating the service information during the providing of the service from the second target terminal. 
 
     
     
       11. The method according to  claim 9 , further comprising managing a status of the service information based on a usable time associated with the service information. 
     
     
       12. The method according to  claim 9 , further comprising:
 allowing a user to set a tag to bypass updating; and 
 bypassing the updating of the service information based on the set tag. 
 
     
     
       13. The method according to  claim 7 , further comprising storing the service information. 
     
     
       14. A system to provide a service from a service provider, the system comprising:
 a terminal with near field communication (NFC) capability; 
 wherein the terminal communicates with a first target terminal that provides the service, 
 wherein the terminal communicates with the first target terminal via NFC, and receives the service from the first target terminal via NFC, and updates service information associated with the service, 
 wherein the service information comprises a standardized format, and 
 wherein the service information comprises: 
 a region to store commands for a processor; 
 an authority status; 
 an identification for the terminal; 
 a list of the services provided; and 
 an availability of the services provided. 
 
     
     
       15. The system according to  claim 14 , wherein the terminal further comprises a storage unit to store the service information. 
     
     
       16. The system according to  claim 14 ,
 wherein the terminal communicates with a second target terminal that provides the service, 
 wherein the terminal communicates with the second target terminal via NFC, and receives the service from the second target terminal via NFC, and updates the service information associated with the service. 
 
     
     
       17. The system according to  claim 16 , wherein the terminal further comprises a data transmitting unit to transmit updated service information to the second target terminal. 
     
     
       18. The system according to  claim 14 , wherein the terminal further comprises a service status processing unit to manage a status of the service information based on a usable time associated with the service information.
